A tank with a square base of 20 cm was
38 filled with water After another 16940 cm
3 of water was poured into the tank, it became
56 full.
- Find the capacity of the tank in litres.
- Find the final height of the water in the tank.
(a)
Fraction of the tank when 16940 cm
3 of water was poured into the tank
=
56 -
38=
2024 -
924=
11241124 of the tank = 16940
124 of the tank = 16940 ÷ 11 = 1540
2424 of the tank = 24 x 1540 = 36960
36960 mℓ = 36.96 ℓ
Capacity of the tank = 36.96 ℓ
(b)
2024 of the tank = 20 x 1540 = 30800
Final height of the water in the tank
=
3080020 x 20 = 77 cm
Answer(s): (a) 36.96 ℓ; (b) 77 cm
